Bezel:
120 click high grip 12H GMT bezel with hardened stainless steel insert and bespoke bi-colour SuperLuminova with Cooper 'S' at 5H that glows blue. The hobnail knurling around the edge is slightly higher than the insert to create a high grip surface for trustworthy operation even when using the palm of a gloved hand.
Straps:
Leather or solid steel bracelet are easily changed and are secured with solid steel screw in bars driven by the five lobe tool included that locks into the socket heads in the bars.
Crown:
The recessed screw-down crown is triple sealed and located out of harm's way at 4H ensuring it won't dig into the wrist and can't get caught or damaged.
Case:
Beadblasted 316L stainless steel case
9H-3H 43mm excluding crown
12H-6H - 52mm max to tip of case shoulders
Maximum thickness 14mm
Dial:
Easy to read at a glance day or night with bold markings for clarity. The hour markers are bold pyramids reminiscent of 1970s military dive watches, brought up to date with our trademark 12-3-6-9 cardinal graphics, printed in C3 or BW9G Superluminova.
Hands:
Clear differentiation between hours, minutes and seconds for minimal chance of confusion. The stubby ‘sword’ hour hand and slender parallel minutes hand are both filled with C3 Superluminova.
Glass:
Flat sapphire glass with internal multi layer anti reflective coating minimises glare for perfect visibility in all light conditions.
Movement:
Seiko NH35 self-winding automatic movement with 42hr power reserve with hack (stop), and hand-winding. Housed inside our shock protection movement housing with elastomer shock absorbers.
Manufacturer's expected movement accuracy: -20/+40sec per day. Typical real world accuracy: +/- 15sec per day.
Caseback
Bolted down using hex bolts creating a perfect compression seal and correct tension for the shock absorption system. Multiple surfaces minimise skin contact for comfort. Caseback engraving will always be vertical as shown.
